Answer:
27/2 which is 13.5
Step-by-step explanation:
Keep the 6 as it is, turn the division into multiplication, and turn the 4/9 to 9/4
(This is a fixed way to treat division)
Now multiply 6 by 9 so you’re left with 54/4
Simplify the fraction you’ll get 27/2. If you use a calculator you’ll get 13.5

ANSWER
Yes, this forms a triangle
EXPLANATION
We want to check if the measurements 11, 11 and 11 can make the side of a triangle.
We will use the Triangle Inequality Theorem.
We have to check if the sum of any of the two measurements will be greater than the third. If yes, then, they can form a triangle and vice versa.
That is:
11 + 11 = 22
Since 22 is greater than 11, the measurements can form a triangle.
